Blu-ray (Blu-ray Disc or BD) is a digital optical disc data storage format. It was invented and developed in 2005 and released worldwide on June 20, 2006. It was designed to supersede the DVD format, capable of storing several hours of high-definition video (HDTV 720p and 1080p).

Triple-layer discs (100 GB) and quadruple-layer discs (128 GB) are available for BD-XL re-writer drives.High-definition (HD) video may be stored on Blu-ray Discs with up to 1920 × 1080 pixel resolution, at 24& 50/60 progressive or 50/60 interlaced frames per second. DVD discs were limited to a maximum resolution of 480 (NTSC, 720×480 pixels) or 576 lines (CCIR 625/50, 720×576 pixels, commonly used with PAL). Besides these hardware specifications, Blu-ray is associated with a set of multimedia formats. The BD format was developed by the Blu-ray Disc Association, a group
